Although the flames of Stromgarde have long since dimmed to ash, the betrayal is not one that was forgotten by the Forsaken. After the fall of Galen at the hands of the Ebon Blade, the undead which followed him into the ruined city that day drew a line regardless of how stalwart their faith was in his leadership. This line was one of high treason, even if by association, in which those who were caught by their former Forsaken comrades were sent to the apothecarium within the Undercity – many of which have not been seen since.
To those to who were fortunate enough to outrun the fetid hand of justice, they would seek asylum within the various other Horde capitals: Thunderbluff and Orgrimmar were relatively safe, but those who attempted to hide within Silvermoon were either rounded up to meet a similar fate to those who were caught early on, or forced into hiding within the Ghostlands.
Rumor has it, however, that the patchwork group named the Defilers of Arathor, despite these astronomical setbacks, are attempting to rally together a force to weather what dark tides may be upon the horizon.
